my lo is 2mth old can i use teat w 2 hole instead of 1? cos 1 hole she tend to drink v slow (30min feeding) TIA

My son seemed impatient with a no 1 teat when he was 2 months old so I moved him to a no 2 teat. And he was fine. Note: the no 2 teat is still 1 hole but it's a wider hole. All bottle manufacturers (philips avent, tommee tippee, etc) have teats of various sizes; and you move up the baby to wider holes as they grow.
